.DRAFT-DEFLECTOR.

SPECIFICATION forming part of Letters Patent No. 794,163, dated July 11,1905.

Application filed May 20, 1904. Serial No. 208,901.

To (LZZ whom, it 11m/ 1j concern:

Be it known that I, JoHNDnLLINGER, a citi- Zen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Draft-Defiectors, ofwhich the following is a specification.

My invention relates to draft deliectors adapted to be secured to thelower portion of a window-frame and to bear against the sill of the samefor the purpose. of directing the air-draft upwardly when thewindow-sash is raised from the bottom to ventilate a room.

ln the drawings, Figure 1 is a front elevation of the draft-deiector,showing the same attached to a window. Fig. 2 is an enlarged view of oneend of the deflector, showing the same in position to be attached to thewindowframe and be forced down against the window-sill. Fig. 3 is asimilar view showing the deflector in place and forced down against thewindow-sill. Fig. 4 is a vertical section taken on line 4 4, Fig. 2, thewindow being slightly raised. Fig. 5 is an enlarged vertical sectiontaken on line 5 5, Fig. 1. Fig. 6 is a horizontal section on line 6 6,Fig. 2. Fig. 7 is avertical section taken on line 7 7 Fig. 2. Fig. 8 isa detailed perspective view of one of the cam-screws by means of whichthe deiiector is locked against the window.

The defiector A is preferably formed of sheet metal and comprises twotelescopic sections B B, each having its upper edge curved, as shown atthe section B having its curved portion fitting within the curvedportion of the section B. The lower marginal portion of the section B iscurved upward upon itself and recurved to form a channeled clampingportion C, in which a strip of felt, rubber, or other suitable materialc is clamped, while the section B has its lower marginal portion bentupward upon itself, as at O', thence curved outward and downward, as atc, and finally bent inward and upward and recurved to form adownwardly-opening channeled clamping portion D, in which a strip offelt or other suitable material (Z is clamped, a downwardlyopeningchannel being formed between the clamping portion D and upwardly-bentportion C', and in said channel the clamping portion O of the section Bis adapted to slide.

This arrangement provides a perfect connection between the two sectionsand renders the device easily adjustable. n

Near each end the deflector is provided with a vertical slot E, havingan enlarged lower end of oval formation c, corresponding somewhat to aninverted keyhole,and the securing means used in connection with the saidslot E consists of two screws F,each having a cam-,shaped or eccentrichead Gr, provided with an outwardly-extending lock-'arm H, each armbeing provided with a lug z., forming a thumbpiece for convenientlymanipulating the said screws. These fastening-screws are screwed intothe sides of the window-frame, and when applying the deflector the arm Hof each screw is turned to a vertical position, which permits of thedeflector being passed over the screws until the edges of the slots Eregister and are brought in line with that portion of the eccentric headG in rear of the arm H of the screws, when a quarter-turn of each screw'will cause the eccentric head to bear against the edge of the enlargedend of the slot E, thereby forcing the deflector down against thewindowsill and locking the same in place', the flexible strip at thelower end of the deflector yielding to accommodate any irregularity inthe window-sill. Thus it will be seen that when my deiiector is inposition in a window and the lower sash of the window is raised for thepurpose of Ventilating a room the deector forms a shield and theoccupants of the room are not exposed to the direct inflow or draft offresh air, asthe same enters the opening caused by the raised sash andpasses up between the deflector and the lower sash.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent,.is

l. The combination with a window, of a deflector comprising twotelescoping sections, one section having its lower marginal portioncurved upward and recurved to form a downwardly-opening channel and theother section having its lower marginal portion bent upon itself, thencecurved outward and downward and finally bent upon itself and recurved toform a downwardly-opening channel, and a flexible strip held in thechannel of each seetion.

2. A draft-defieotor comprising two telescoping sections having theirlower ends curved to form two parallel downwardly-opening ohlannels, andflexible strips held in said channe s.

3. A draft-deiiector comprising two telescoping sections, one of saidsections having a downwardly-opening channel, and the other sectionhaving two down wardly-opening Channels in one of which the channeledportion of the first-mentioned section is slidably located, the otherchannel of the second-mentioned section and the channel of thetiret-mentioned section being provided with iiexible strips whichproject therefrom.`

t. The combination with a window-frame, of a detlector in Contact withsaid frame and having an opening at each end thereof, and afastening-screw for each opening consisting of a screw portion embeddedin the frame, an eccentric head adapted for engagement with the edge ofsaid opening to force the deileetor in Contact with the windowsill, anda lookarm extending from said head for looking the defieotor against thewindow-frame.

5. The combination with a window-frame, of a defieetor in Contact withsaid frame and having at each end a vertical slot enlarged at its lowerend, and a fastening-screw for each slot consisting of a screw portion,an eccentrie head held in the enlarged lower end of said slot, and alock-arm extending from saidl head and adapted to look the defleotor tothe window-frame.

6. The combination with a window-frame, of a detleetor in Contact withsaid frame and having an opening at each end, and fastening meansadapted to force the deleetor against the upper surface of thewindow-sill and look the same to the window-frame.

In testimony whereoi` l have a'HiXed my signature in the presence of twosubscribing witnesses.
